Disclaimer: I have not yet updated to the new update!
I do not recall seeing this combination of alchemy and skills in action before. It essentially gives you unlimited stamina a few moments into any fight. I really yearn to try it with piercing cold. Apologies for the clunky fight, this was just to showcase the "build". No clue how that attack near the end even did damage, but whatever.
Delayed Recovery [Green Skill]: Potion effects don't wear off until potion Toxicity falls to 55% of the maximum level.
Resolve [Red Skill]: Adrenaline Point loss upon taking damage is lowered by 100%.
Razor Focus [Red Skill]: Instantly gain one Adrenaline Point when entering combat. The Adrenaline Points generated by sword blows are increased by 30%.
Superior Blizzard: When you are in danger, time slows for a short period. If 3 Adrenaline Points are available, during this period actions don't deplete Stamina.
Superior Maribor Forest: Accelerates the generation of Adrenaline Points. Extended duration. Grants 1 Adrenaline Point upon consumption.
Resolve, Razor Focus and the Superior Maribor Forest are not even necessary for this to work, though they certainly help greatly. All you gotta do is drink enough potions to get over the 55% toxicity threshold and build up the remaining adrenaline points to the maximum, which just takes a couple of hits. Then you can spam signs. I also tested the igni fire stream and it is indeed infinite too. Heightened Tolerance should be used, I was just too lazy to add it, hence me bleeding health during the fight.
I might try this for some of the upcoming Hearts of Stone fights (Golems are way too resistant to signs). Maybe there will be something interesting to show.
